Personal Reg Plates on a Lease
You can indeed have your personal reg plates on your lease car. However, All Car Leasing are unable to facilitate this change. To do so, speak with your finance company as soon as the deal is confirmed who will then assist you via the DVLA to get the plates changed.
Because the finance company have the logbook and you are the registered keeper this can not be done by yourselves but it still a very simple process.
